Asshown in FIG. 1, a device A is a hotspot terminal, and the device A isused as an application access point (AP) of a wide area network (WAN) tolog in to a remote network. A device B is a mobile terminal on a localarea network (LAN) side, and the mobile terminal accesses a wirelesslocal area network (WLAN) established by the device A that is used as anAP, so as to implement data services, such as watching a video, browsinga web page, instant messaging, or listening to music. In the applicationscenario of this embodiment of the present invention, a person whooperates the device A is referred to as an administrator, and a personwho operates the device B is referred to as a user.

FIG. 2 is a schematic diagram of an application scenario in which amobile terminal accesses a wireless local area network established by ahotspot terminal according to another embodiment of the presentinvention. As shown in FIG. 2, a device A is a hotspot terminal and isused as an application access point of a WAN to log in to a remotenetwork. A device B is a mobile terminal on a LAN side, and the mobileterminal accesses a WLAN established by the device A that is used as anAP, so as to implement data services, such as watching a video, browsinga web page, instant messaging, or listening to music. A device C is amobile terminal on the LAN side and is referred to as a managementterminal. In the application scenario of this embodiment of the presentinvention, a person who operates the device C is referred to as anadministrator, and a person who operates the device B is referred to asa user.

In the present invention, a mobile terminal involved may be, forexample, a mobile phone, a personal computer (PC), a tablet computer, adigital camera, and a game console. A hotspot terminal may be, forexample, a wireless router, a portable router, a wireless modem, amobile phone, a PC, a tablet computer, and a digital camera. Amanagement terminal may be, for example, a mobile phone, a PC, a tabletcomputer, a digital camera, and a game console.

In the prior art, to ensure security of a mobile terminal that accessesa wireless local area network, a hotspot terminal establishes a wirelesslocal area network for which a password is set. A correct password needsto be entered for the mobile terminal to access an encrypted WLANestablished by the hotspot terminal, so as to implement a data service.In some application scenarios, when the mobile terminal accesses theencrypted WLAN established by the hotspot terminal, the followingproblems are likely to occur: it is difficult to enter the password, orit is difficult to acquire the password because the password is toocomplex; or any mobile terminal can access the encrypted WLAN when thepassword is disclosed. As a result, a process in which the mobileterminal accesses the encrypted WLAN established by the hotspot terminalis tedious and complex.

FIG. 3 is a schematic flowchart of a network connection method accordingto an embodiment of the present invention. The method includes thefollowing steps:

S301. A hotspot terminal receives an Internet access request sent by amobile terminal.

The Internet access request is sent to the hotspot terminal after themobile terminal accesses, according to a service set identifier (SSID)of the hotspot terminal, an unencrypted WLAN established by the hotspotterminal. When the mobile terminal accesses, according to the SSID ofthe hotspot terminal, the unencrypted WLAN established by the hotspotterminal, the hotspot terminal acquires a MAC address of the mobileterminal, where the MAC address of the mobile terminal is used touniquely identify the mobile terminal.

The SSID of the hotspot terminal may be broadcasted by the hotspotterminal in a wireless fidelity (Wi-Fi) manner, or may be broadcasted bythe hotspot terminal in another manner, such as near field communication(NFC).

The Internet access request may be specifically a request for logging into a website, such as sina (a news website), yahoo, sohu (a videowebsite), or youku (a video website); or a request for logging in toanother application program that requires Internet access, such as MSNor QQ (a chat tool).

When the mobile terminal finds the SSID of the hotspot terminal, themobile terminal requests to access, according to the found SSID of thehotspot terminal, the WLAN established by the hotspot terminal. Thehotspot terminal establishes the unencrypted WLAN, that is, the mobileterminal may access, according to the SSID, the unencrypted WLANestablished by the hotspot terminal in a case in which no password needsto be entered.

FIG. 4 is a schematic diagram of an user interface showing that a mobileterminal finds an SSID of a hotspot terminal; as shown in FIG. 4, themobile terminal finds an SSID that does not require password entering:E5730-Open, and the mobile terminal may access, according to theE5730-Open, an unencrypted WLAN established by the hotspot terminal.

After the mobile terminal accesses the unencrypted WLAN established bythe hotspot terminal, the mobile terminal sends, according to a userrequirement such as watching a video, browsing a web page, instantmessaging, or listening to music, an Internet access request to thehotspot terminal to request to log in to a remote network by using thehotspot terminal. For example, the mobile terminal requests to log in tosina (a news website), yahoo, sohu (a video website), or youku (a videowebsite) by using the hotspot terminal.

S302. The hotspot terminal sends an input request to the mobile terminalaccording to the received Internet access request, where the inputrequest is used to request the mobile terminal to send user identityinformation.

When the hotspot terminal receives the Internet access request sent bythe mobile terminal, the hotspot terminal sends the input request to themobile terminal according to the received Internet access request.Specifically, the mobile terminal requests to log in to a remote networkby using the hotspot terminal, and the hotspot terminal prevents,according to the received Internet access request, the mobile terminalfrom logging in to the remote network, and sends the input request tothe mobile terminal to request the mobile terminal to send the useridentity information. The user identity information is used to identifya user who uses the mobile terminal, and the user identity informationmay include at least one piece of information of a user name, a usernickname, a user phone number, and user convention information. Theforegoing at least one piece of information of a user name, a usernickname, a user phone number, and user convention information is usedto enable an administrator to distinguish an identity of the user.

In another embodiment of the present invention, the hotspot terminalprevents, according to the received Internet access request, the mobileterminal from logging in to the remote network and sends the inputrequest to the mobile terminal, which may be implemented by the hotspotterminal in a redirection manner. That is, the hotspot terminalredirects the Internet access request sent by the mobile terminal to theinput request in the redirection manner. For example, the mobileterminal requests to log in to sina, and the hotspot terminal sends aninput request to the mobile terminal in the redirection manner; FIG. 5Ais an example of a specific display user interface of the input request.

FIG. 5A is a schematic diagram of an user interface showing that ahotspot terminal sends an input request to a mobile terminal. As shownin FIG. 5A, the hotspot terminal sends, according to the receivedInternet access request, the input request to the mobile terminal torequest the mobile terminal to send the user identity information.

The user identity information that requires to be entered is displayedon the schematic diagram of the user interface in FIG. 5A, and forexample, may include any one or more of the following information:permission application information, a nickname, and a user phone number.

S303. The hotspot terminal receives the user identity information sentby the mobile terminal.

The user identity information may be, for example, at least one piece ofinformation of a user name, a user nickname, a user phone number, anduser convention information. The user convention information may be anyinformation about a convention between the user and the administrator,such as a piece of specific text and a string of specific numbers.

FIG. 5B is a schematic diagram of an user interface of user identityinformation that is sent by a mobile terminal and received by a hotspotterminal. The schematic diagram of the user interface in FIG. 5B is usedas an example for description.

A user enters user identity information according to the user identityinformation that is displayed on the user interface and requires to beentered; for example, the entered user identity information includesthat permission application information is “I am Li Si, and I want tolog in to a remote network by using your AP; please approve” and that anickname is “Tom”. The user identity information sent by the mobileterminal to the hotspot terminal is the permission applicationinformation “I am Li Si, and I want to log in to a remote network byusing your AP; please approve” and the nickname “Tom”.

It should be noted that a display user interface of the mobile terminalmay further include other content, such as “Please notify me of anapproval result by an SMS message”, and the user may choose whether toreceive the approval result by an SMS message; if the user chooses toreceive the approval result by an SMS message, the user may fill in aphone number for receiving the SMS message. In addition, the displayuser interface of the mobile terminal may further include descriptionabout a current WLAN, such as “E5730-Open”, and “This is a wirelessrouter of Zhang San”.

S304. The hotspot terminal receives a permission confirmationinstruction that is entered by an administrator according to the useridentity information.

Similarly, the schematic diagram of the user interface in FIG. 5B isused as an example for description. After the user enters the useridentity information and the user clicks for confirmation (for example,clicks “Apply for Internet access”), the hotspot terminal receives theuser identity information sent by the mobile terminal, and the useridentity information displayed on the user interface includes thepermission application information “I am Li Si, and I want to log in toa remote network by using your AP; please approve” and the nickname“Tom”.

Optionally, the user identity information sent by the mobile terminalmay include only the permission application information, or may includeonly the nickname, or may be other identity information that is used toenable the administrator to identify the user, for example, at least oneof a user name, a user phone number, or user convention information.

There may be two manners in which the hotspot terminal receives thepermission confirmation instruction that is entered by the administratoraccording to the user identity information.

One manner is as follows: The hotspot terminal sends the user identityinformation to a management terminal, and the hotspot terminal receivesthe permission confirmation instruction sent by the management terminal,where the permission confirmation instruction is entered by theadministrator according to the user identity information displayed bythe management terminal.

For example, the hotspot terminal sends the user identity information tothe management terminal, and the user identity information includes “Iam Li Si, and I want to log in to a remote network by using your AP;please approve” and the nickname “Tom”.

The user identity information displayed on an user interface of themanagement terminal includes the permission application information “Iam Li Si, and I want to log in to a remote network by using your AP;please approve” and the nickname “Tom”. According to the user identityinformation displayed by the management terminal, including thepermission application information “I am Li Si, and I want to log in toa remote network by using your AP; please approve” and the nickname“Tom”, the administrator enters the permission confirmation instructionby operating a touchscreen of the management terminal, or pressing aphysical button of the management terminal, or in another manner.

In the other manner, receiving, by the hotspot terminal, the permissionconfirmation instruction that is entered by the administrator accordingto the user identity information specifically includes: displaying, bythe hotspot terminal, the user identity information, and receiving, bythe hotspot terminal, the permission confirmation instruction that isentered by the administrator according to the user identity information.

For example, the user identity information is displayed on an userinterface of the hotspot terminal, and the user identity informationincludes the permission application information “I am Li Si, and I wantto log in to a remote network by using your AP; please approve” and thenickname “Tom”.

According to the user identity information displayed by the hotspotterminal, including the permission application information “I am Li Si,and I want to log in to a remote network by using your AP; pleaseapprove” and the nickname “Tom”, the administrator enters the permissionconfirmation instruction by operating a touchscreen of the hotspotterminal, or pressing a physical button of the hotspot terminal, or inanother manner.

S305. The hotspot terminal determines Internet access permission of themobile terminal according to the received permission confirmationinstruction.

The hotspot terminal determines, according to the received permissionconfirmation instruction that is entered by the administrator accordingto the user identity information, whether the mobile terminal can log into a remote network by using the hotspot terminal.

In this embodiment of the present invention, when a hotspot terminalreceives an Internet access request of a mobile terminal, the hotspotterminal sends an input request to the mobile terminal, and the hotspotterminal receives a permission confirmation instruction that is enteredby an administrator according to user identity information, anddetermines Internet access permission of the mobile terminal accordingto the received permission confirmation instruction. A problem thatentering a password when the mobile terminal logs in to a remote networkby using the hotspot terminal is complex and tedious is resolved. Aconvenient and efficient method for performing network connection by themobile terminal by using the hotspot terminal is provided under thepremise of ensuring that the mobile terminal can securely log in to theremote network by using the hotspot terminal.

FIG. 6 is a schematic flowchart of a network connection method accordingto another embodiment of the present invention. The method includes thefollowing steps:

S601. A mobile terminal accesses, according to an SSID of a hotspotterminal, an unencrypted WLAN established by the hotspot terminal.

The hotspot terminal establishes the unencrypted WLAN, that is, themobile terminal may access, according to the SSID, the unencrypted WLANestablished by the hotspot terminal in a case in which no password needsto be entered. For example, the mobile terminal finds an SSID that doesnot require password entering: E5730-Open, and the mobile terminal mayaccess, according to the E5730-Open, an unencrypted WLAN established bythe hotspot terminal.

The SSID of the hotspot terminal may be broadcasted by the hotspotterminal in a Wi-Fi manner, or may be broadcasted by the hotspotterminal in another manner, such as NFC.

When the mobile terminal accesses, according to the SSID of the hotspotterminal, the unencrypted WLAN established by the hotspot terminal, thehotspot terminal acquires a MAC address of the mobile terminal, wherethe MAC address of the mobile terminal is used to uniquely identify themobile terminal.

S602. The mobile terminal sends an Internet access request to thehotspot terminal.

The Internet access request may be specifically a request for logging into a website, such as sina (a news website), yahoo, sohu (a videowebsite), or youku (a video website); or a request for logging in toanother application program that requires Internet access, such as MSNor QQ (a chat tool).

After the mobile terminal accesses the unencrypted WLAN established bythe hotspot terminal, the mobile terminal sends, according to a userrequirement such as watching a video, browsing a web page, instantmessaging, or listening to music, an Internet access request to thehotspot terminal to request to log in to a remote network by using thehotspot terminal. For example, the mobile terminal requests to log in tosina (a news website), yahoo, sohu (a video website), youku (a videowebsite), or the like by using the hotspot terminal.

S603. The hotspot terminal sends an input request to the mobile terminalaccording to the received Internet access request.

The input request is used to request the mobile terminal to send useridentity information.

When the hotspot terminal receives the Internet access request sent bythe mobile terminal, the hotspot terminal sends the input request to themobile terminal according to the received Internet access request.Specifically, the mobile terminal requests to log in to a remote networkby using the hotspot terminal, and the hotspot terminal prevents,according to the received Internet access request, the mobile terminalfrom logging in to the remote network, and sends the input request tothe mobile terminal to request the mobile terminal to send the useridentity information. The user identity information is used to identifya user who uses the mobile terminal, and the user identity informationincludes at least one piece of information of a user name, a usernickname, a user phone number, and user convention information.

In another embodiment of the present invention, the hotspot terminalprevents, according to the received Internet access request, the mobileterminal from logging in to the remote network and sends the inputrequest to the mobile terminal, which may be implemented by the hotspotterminal in a redirection manner. That is, the hotspot terminalredirects the Internet access request sent by the mobile terminal to theinput request in the redirection manner. For example, the mobileterminal requests to log in to sina, and the hotspot terminal sends aninput request to the mobile terminal in the redirection manner; FIG. 5Ais an example of a specific display user interface of the input request.

S604. The mobile terminal sends user identity information to the hotspotterminal according to the received input request.

The user identity information may be, for example, at least one piece ofinformation of a user name, a user nickname, a user phone number, anduser convention information.

S605. The hotspot terminal displays the received user identityinformation.

A schematic diagram of an user interface in FIG. 5B is used as anexample for description, and permission application information that isentered by the user according to a requirement displayed on the userinterface is “I am Li Si, and I want to log in to a remote network byusing your AP; please approve.” The user identity information sent bythe mobile terminal to the hotspot terminal is the permissionapplication information “I am Li Si, and I want to log in to a remotenetwork by using your AP; please approve” and a nickname “Tom”.

S606. The hotspot terminal receives a permission confirmationinstruction that is entered by an administrator according to the useridentity information.

The administrator enters the permission confirmation instructionaccording to the user identity information displayed by the hotspotterminal.

For example, the user identity information is displayed on an userinterface of the hotspot terminal, and the user identity informationincludes the permission application information “I am Li Si, and I wantto log in to a remote network by using your AP; please approve” and thenickname “Tom”.

According to the user identity information displayed by the hotspotterminal, where the user identity information includes the permissionapplication information “I am Li Si, and I want to log in to a remotenetwork by using your AP; please approve” and the nickname “Tom”, theadministrator enters the permission confirmation instruction byoperating a touchscreen of the hotspot terminal, or pressing a physicalbutton of the hotspot terminal, or in another manner.

S607. The hotspot terminal determines Internet access permission of themobile terminal according to the received permission confirmationinstruction.

The hotspot terminal determines, according to the received permissionconfirmation instruction that is entered by the administrator accordingto the user identity information, whether the mobile terminal can log into a remote network by using the hotspot terminal.

In another embodiment of the present invention, after the hotspotterminal performs step S607 and determines that the mobile terminal hasthe Internet access permission, the hotspot terminal may further performstep S608.

S608. The hotspot terminal sets, according to a preset Internet accesscondition, an Internet access limitation of accessing the hotspotterminal by the mobile terminal.

The Internet access limitation may be specifically time of accessing theunencrypted WLAN established by the hotspot terminal, or an Internetaccess range, or a bandwidth limitation.

Optionally, the Internet access limitation may be set by theadministrator, or the Internet access limitation may be set according toa result of searching for, by the hotspot terminal according to the MACaddress of the mobile terminal, an Internet access condition of themobile terminal in a pre-stored whitelist.

According to MAC addresses of mobile terminals, the hotspot terminal mayset time of accessing, by different mobile terminals, the unencryptedWLAN established by the hotspot terminal, or set Internet access rangesof different mobile terminals, or set bandwidth limitations of differentmobile terminals, as shown in Table 1.

TABLE 1 Example: Access Bandwidth MAC address time Internet access rangelimitation 44-45-53-54-00-00 10 min Limited to a news web page  2 Mbit/s44-45-53-54-00-01 30 min Limited to a news web page 10 Mbit/s

For a mobile terminal that has Internet access permission, which isdetermined by the hotspot terminal, the hotspot terminal may establish awhitelist; when the mobile terminal in the whitelist sends an Internetaccess request again, the hotspot terminal may search the whitelist anddetermine Internet access permission and an Internet access limitationof the mobile terminal according to the whitelist.

In another embodiment of the present invention, after the hotspotterminal performs step S607 and determines the Internet accesspermission of the mobile terminal, the hotspot terminal may furtherperform step S609.

S609. The hotspot terminal sends reminder information to the mobileterminal.

The reminder information is used to remind whether the Internet accessrequest of the mobile terminal is approved.

In this embodiment of the present invention, when a hotspot terminalreceives an Internet access request of a mobile terminal, the hotspotterminal sends an input request to the mobile terminal, and the hotspotterminal receives a permission confirmation instruction that is enteredby an administrator according to user identity information, anddetermines Internet access permission of the mobile terminal accordingto the received permission confirmation instruction. A problem thatentering a password when the mobile terminal logs in to a remote networkby using the hotspot terminal is complex and tedious is resolved. Aconvenient and efficient method for performing network connection by themobile terminal by using the hotspot terminal is provided under thepremise of ensuring that the mobile terminal can securely log in to theremote network by using the hotspot terminal.
